TI  - Hip internal and external rotation range of motion reliability in youth baseball 
      players.

AB  - BACKGROUND: Impaired hip range of motion has been related to increased injury 
      risk in baseball players. However, no hip rotation range of motion (ROM) 
      reliability studies have been performed in youth, which cannot be assumed to be 
      comparable to adults. This study aimed to: 1) assess the inter- and intra-rater 
      reliability of hip rotation passive ROM in youth baseball players; 2) calculate 
      the standard error of measurement (SEM) and minimum clinically important 
      difference (MCID). METHODS: Hip external (ER) and internal (IR) rotation were 
      measured. Inter and intra-rater reliability were assessed through intraclass 
      correlation coefficients (ICC) and 95% Confidence interval (95% CI), with SEM and 
      MCID. Bland-Altman plots were used to assess overall measurement bias. RESULTS: 
      Nineteen youth baseball players participated. Hip ER intra-rater ICC was 
      excellent (tester one: 0.983 (0.965, 0.993); tester two: 0.952 (0.903, 0.980) and 
      hip IR was excellent (tester one: 0.965 (0.927, 0.985); tester two: 0.965 (95%CI: 
      0.928, 0.985). Hip ER SEM was 3.2 degrees, and hip IR was 2.2 degrees. Hip ER 
      MCID was 7.5 degrees, and hip IR was 5.1 degrees. Bland-Altman plots for hip ER 
      and IR did not detect any bias. CONCLUSIONS: Hip ROM inter-rater and intra-rater 
      reliability was excellent for use in youth baseball players, with no rater bias. 
      Sports medicine professionals can reliably assess supine hip rotation ROM in 
      youth baseball players. This ROM methodology can be easily administered within 
      the clinic or pitch-side, and interpret the results, increasing its real-world 
      applicability.
